My hens are ALL molting now? why?

[Onslow's Hens]

Thanks everyone for all the advise! My flock is all feathered backout and I got 4 eggs on Saturday and 6 on Sunday! Looks like we are back up and running! The Game Bird feed was a Southern States - Super Breeder formula and it worked terrific. I have now switched them to the southern States all grain layer formula. They are tearing it up and everyone seems back to normal and free ranging like the little raptors they are! Mice and frogs beware - the girls are back in town.
